Hey Foneguy, I'd recommend the following books:
Persuasion Engineering, by Richard Bandler and John Lasalle. Great book, transcripted from a seminar about getting yourself into the proper state for selling and creating good feelings in yourself and the clint.
and
Unlimited Selling Power by Donald Moine adn Kenneth Lloyd. They show you how to apply Ericksonian conversational hypnosis (the same type Paul Scheele uses in the paraliminals) to the selling procedure.
Another one you might try out is
High Probability Selling by Jacques Werth.
If you're gonna be doing a lot of cold calling, this is the book to get.
I would also highly recommend the previously recommended paraliminals, sales leap, self esteem supercharger, and of course natural brilliance, ideal mindset, decisive action, consistent achievement.
Good Luck (luck of course meaning preparation meeting opportunity)!
George
